No, I was trying to say that XD cards only went up to 128MB (having seem someone hawking a 64MB one for loadsamoney on Amazon), but it seems I was mistaken. I forget when Olympus and Fuji stopped making cameras that took those cards, but it was at least a decade ago I think, although thinking it through, back then I would have been buying 2GB microSD cards (and 8GB CF cards), so perhaps it going up to that size fits. I guess there were probably multiple revisions though, with increased block sizes as time went on, but older devices might not know about the later block sizes, so be unable to use bigger cards. It's possible the GP32 only supported early generations of that filesystem, but I don't know either way myself. I thought the GP32 was cool, but by the time I became aware of it the GP2X was nearing release.
